Joined by his deputy six-year-old Myah Rose Wilson, from Sunderland, the pair were introduced as part of the half-term Metro Gnomes show at the shopping centre.

The pair were chosen after a hard-fought contest for the post where entrants had to explain in 200 words why they should be the ‘head of fun’.

Mackenzie submitted a video entry explaining why he was the lad for the job.

Dressed in miniature Metrocentre uniforms the pair looked the part as they took to the stage in the shopping centre’s Exhibition Square.

Mackenzie said: “I’ve enjoyed today. I think I was lucky when I got the job.

“So far I’ve had to walk around giving out sweets. I like my suit.”

Deputy, Myah Rose added: “I said how much I like the Metro Gnomes. I don’t really know what else we’ve got to do but it’s very exciting.”

Among their tasks – which they will carry out in school holidays and half terms breaks – Mackenzie and Myah will test out the centre’s children’s areas as well as testing new restaurants and leisure activities for child friendliness.

Later this year they will get to meet Santa and his elves testing all the toys set to be sold in the centre this Christmas.

In exchange for their hard work, Mackenzie and Myah will be paid handsomely in gift vouchers and toys.
